Abstract:

In TREC2002, we participated in three tracks web, novelty and adaptive filtering. The Web track has two tasks distillation and named-page retrieval. Distillation is a new utility concept for ranking documents, and needs new design on the output document ranked list after an ad-hoc retrieval from the web .gov collection. Novelty track is a new task that involves identifying relevant sentences to a question, and to remove duplicate or non-novel entries in the answer list. The third track is adaptive filtering. We revived a filtering program that was functional at TREC-9 with some added capability. Sections 2, 3, 4 describe our participation in these tracks respectively. Section 5 has our conclusion.
